4-axis oil tanker trucks are heavy-duty vehicles designed for high-capacity fuel transport, typically featuring capacities ranging from 20,000L to over 50,000L. These trucks often use carbon steel or aluminum alloy tanks for transporting gasoline, diesel, and crude oil, with enhanced safety features like emergency valves and spill containment.
Key Features and Configurations
- Axle Configuration: Often 8×4 (two steerable front axles, two driven rear axles), designed for increased capacity and stability.
- Tanker Materials: Carbon steel for durability or aluminum alloy for lighter weight and increased payload capacity.
- Capacity: Ranges widely, with common 4-axis rigid trucks holding 20,000L-25,000L, while 4-axle trailer combinations can exceed 40,000L-50,000L.
- Safety Equipment: Equipped with fire suppression systems, top loading/unloading systems, and pressure relief valves.
- Applications: Used for transporting petroleum products, chemical liquids, and edible oils.
